"Some day we'll find where we belong / Tōku whenua turaikura."
In August, Walker spoke to the Herald and called his family his "biggest flex".
"Before being a singer, I dreamed of being a dad and a husband," he shared.
Walker proposed to Tyson last December, and is a stepdad to little Te Puuwairua.
"She's the most beautiful woman in the world inside and out. Every time I look at them, I'm so blessed."
The couple's wedding video was filmed by Rawhai Wetere and edited by Shae Sterling.
Matemateāone was co-written by Stan with Devin Abrams, Isiah Ngawaka, Mikey Dam and Ruth Smith, and will feature on his upcoming album Te Arohanui out September 17, during Māori Language Week, on Sony Music NZ.
The album will be Walker's first-ever te reo Māori album.
"It was inevitable that I would release a reo Māori album. It wasn't a matter of if, but when. Now is the perfect time," Walker shared in a statement.
"Being Māori, nō Ngai Te Rangi, Ngāti Pūkenga, Tūhoe, Ngāti Porou, Tūhourangi, Ngāti Wāhiao, Ngāti Pikiao, Ngāi Tahu, it is in my DNA, it is in my blood. I credit my voice and all that it holds to all those who have come before me. My tupuna fought and died so that I, we could be all that we should be."
